Lightweight Gear Assembly
An engineering team needed a working gear pair for a compact drive prototype — true tooth profiles that mesh smoothly, at a fraction of machined-gear cost and lead time.

Overview
Teeth that mesh first try
The brief called for a driver and driven gear with lightening pockets — geometry no hob could cut in one setup. SLS nylon gave stiff, wear-tolerant teeth straight off the build.
We nested the pair with witness coupons, cleared every pocket of powder and checked tooth profiles against the client's datum scheme before dispatch.
Challenge & Approach
Light gears, true profiles
- Profile offset tuned so the printed pair meshes without binding.
- Pocketed hubs cut rotating mass while keeping the rim stiff.
- First-article report on bore fit and backlash before batch release.
